Question 1
Which statement best describes kin selection and inclusive fitness?
Correct Answer:
Kin selection favors helping relatives reproduce; inclusive fitness combines direct reproduction with indirect genetic contributions via relatives.
Explanation:
Kin selection centers on the idea that helping relatives can spread an individual’s genes because relatives share copies of those genes. Inclusive fitness then combines two sources of genetic propagation: direct fitness from one's own offspring and indirect fitness gained when helping relatives reproduce, weighted by how closely related those relatives are. This aligns with Hamilton's rule, which says altruistic behavior is favored when the relatedness times the benefit to the relative exceeds the cost to the actor. So the statement is correct because it explicitly describes kin selection as promoting relatives’ reproduction and defines inclusive fitness as the sum of direct reproduction plus indirect genetic contributions via relatives. The other options miss these relationships: kin selection isn’t about ignoring relatives, Hamilton’s rule is central to kin selection, and inclusive fitness isn’t limited to population-level effects but concerns an individual's genetic contribution that includes relatives.
Question 2
Which group typically invests a lot of energy in the mating process?
Correct Answer:
Females
Explanation:
Energy cost of reproduction is uneven between sexes, and the sex that typically spends the most energy during mating is the one investing more in offspring. Producing eggs is energetically expensive, and in many species females also carry pregnancies and, after birth, provide substantial care or nutrition (like lactation). That hefty energy demand means mating and reproduction are high-cost investments for females, shaping behaviors like selective mate choice and strategic timing to maximize offspring survival. While males often expend energy in courtship and competition, the overall energy burden during the mating process tends to be greater for females. There are exceptions—some species feature substantial male parental care or biparental care—but the general pattern is that females invest more energy in reproduction, making them the group that typically dedicates more energy to mating.
Question 3
What are potential benefits and costs of maintaining a dominance hierarchy?
Correct Answer:
Benefits include predictable resource access and reduced conflict; costs involve energy expenditure, injury risk, and potential reproduction limitations.
Explanation:
Dominance hierarchies create a stable structure for resource access, which means individuals can predict who gets what and when. That predictability reduces frequent fighting, so the overall level of conflict drops and injuries and energy spent on aggression are minimized. At the same time, maintaining a rank costs energy through displays, patrols, and monitoring, and it carries real injury risk if challenges arise. The social arrangement can also limit reproduction for those lower in the hierarchy, as access to mates may be restricted or stress from social status can affect fertility. So the best answer highlights predictable resource access and reduced conflict as benefits, with costs including energy expenditure, injury risk, and potential reproduction limitations. Unstable or opposite aspects—like unpredictable resource access, or benefits of more aggression, or the idea of equal sharing with no costs—don’t fit how dominance hierarchies operate.
Question 4
Which migratory cue relies on Earth's magnetic field (magnetoreception)?
Correct Answer:
Sun compass
Explanation:
Magnetoreception is the ability to sense Earth's magnetic field and use its direction to navigate. Migratory animals can detect the inclination and intensity of the field to determine heading, effectively acting as a magnetic compass that helps them orient toward their destination. This is distinct from a sun-based cue, which relies on the Sun’s position and an internal clock, or a star-based cue, which uses celestial patterns. Landmarks and olfactory cues provide local environmental information rather than global magnetic information. So the cue that relies on Earth's magnetic field is the magnetic field cue, reflecting magnetoreception in navigation.
Question 5
Which phenomenon occurs when prior learning blocks the acquisition of a new association?
Correct Answer:
Blocking
Explanation:
Blocking is when prior learning prevents a new cue from forming a strong association with the outcome. If a subject has already learned that a cue predicts the outcome, introducing a new cue together with the old one doesn’t add surprise or prediction error. Since the outcome is already fully predicted by the first cue, there’s no error signal to drive learning about the new cue, so the new cue fails to acquire its own association. This highlights that learning hinges on surprise: associative strength is allocated to cues that help predict what will happen next. Once the outcome is no longer surprising, additional cues don’t gain strength. For context, acquisition is the initial formation of an association, generalization is responding to cues similar to the learned one, and extinction is the decline of the response when reinforcement stops.
